Near their upper ends, rods 8 are interconnectedby a crossrod 9 which is welded thereto, and handhold knobs 10 areprovided on the upper ends ofthe rods 8.

The slide Ca is mounted on rods 8 for adjustment longitudinally thereofand, for. this purpose, comprises a pair of sleeves lll interconnectedby crossmembers l2, 12. Slide Ca is secured in adjusted position onupright supporting framework Ba by means of setscrews l3, 13. Slide Cadisengageably sup ports the small armchair Da.

Armchair Da includes a bottom sent support 14 having on its uppersurface a pair of longitudinally extending guides IS. A pair of arms 16are secured to opposite sides of seat support 14 and to the back of thearmchair, which latter is supported with its bottom edge spaced somewhatabove the guides I5, as will be clear from FIG. 4. Seat Ea is provided,on its under surface, with a pair of guides 17; 17 which arecomplementary to the guides 15 and provide for longitudinal adjustmentof seat Ea with respect to seat support M. Guides 17 are provided withrespective stops or abutments I7, and guides 15 are provided withabutments 15', the abutments l5 and 17' limiting the magnitude of therelative adjustment of seat Ea longitudinally relative to seat support14. It will be understood that guides 15 and 17 may be replaced by othersimilar guide means, such as pads, rollers, or the like.

Support Fa for footrest Ha comprises a tube 24 which is bent into-arectangular U-shape, each of the opposite legs being bent at a pointsomewhat spaced from the bight to provide generally horizontal legportions and generally downwardly extending leg portions. Notches 24'are provided in spaced relation along each generally horizontallyextending leg portion, and apertures 24" are formed in each downwardlyextending leg portion. Notches 24' are formed in the undersides of thehorizontally extending leg portions, for a purpose to be described.

Device Ga, for the displacement in depth of support Fa of the footrest,comprises two L-shaped or angle side plates 20, fixed to the armrests 16of the small airmchair and having tubes or sleeves 21 welded to theirhorizontal legs.

Tubes 21 slidably receive the ends'of tube 24, and the latter may befixed in several adjusted positions by small hairpin springs 23 securedon seat support 14 and having legs acting through slots 22 oftube 21against notches 24 oftube 24.

Frame la supporting footrest Ha comprises a generally rectangularU-shaped rod 25 with substantially vertically extending legs and with abight portion bent to extend horizontally. Rod 25 has hook-shaped endsand is provided with pro jecting pins 25'. The bight portion of rod 25is provided with aper ured brackets 26 welded thereto and brackets 26are arranged to have footrest Ha disengageably secured thereto, as by SIrews or the like. The hook-shaped portions 25 and 25 are engageable inthe apertures 24" of support Fa, for vertical adjustment of footrestI-Ia relative to small armchair Da.

The devices Ma are in the form of two L-shaped or angle plates, fixed tothe back of the small armchair, and having vertically extending tubeswelded thereto. These tubes receive the vertical legs ofa pair of hooksl8 and 19, these legs being welded together in such a way that books 18and 19 extend at right angles to each other. The books 18 serve tosupport the small armchair on the upper crossmember 12 of slide Ca, withthe back of the small armchair engaging the lower crossmember 12. Whenthe small armchair is removed from slide Ca, the double books may beturned so that hooks 19 extend rearwardly for mounting the smallarmchair on the back of a car seat.

Finally, the tubular frame Sa supporting board or tray Ta isdisengageably connected to the small armchair so that tray Ta may beturned over or inverted with respect to the latter.

A further improved embodiment of the high chair forming the subjectmatter of the invention is shown in FIGS. 5 through 9, and has thefollowing features:

a. the base framework and the rear support one are made in one piecepreferably of metal, shaped so that the high chair is perfectly balancedand cannot be turned over by the child;

. the frame has-fixed thereto and detachable therefrom the supportingboard or tray, which can no longer be inverted but is connected to thesmall armchair for longitudinal adjustment and is removable therefrom;

. the vertically adjustable sliding device has the upper horizontal tubeoutwardly bent so as to permit a better arrangement of the smallarmchairm, once it is removed from the supporting framework, against theback of the car seat;

d. the seat of the small armchair has fixed underneath it, in the restposition, a tubular U-shaped support outwardly rotatable so as to permitplacing of the small armchair, once removed, even on the floor;

e. the footrest is in one piece with its frame, it may be ad justedlongitudinally and it is removable the same as the frame supporting theboard or tray; and

f. the seat is provided with a front extension which serves as a coverfor the footrest.

As may be seen from FIGS. 5 to 9, the high chair comprises a baseframework A movable on four wheels A, and in one piece with a rearsupporting framework B, on which are provided suitable handles L to liftit or displace it.

A slide comprising two horizontal tubes G connected to two verticalsleeves C, is vertically slidable, together with the small armchairdisengageably mounted thereon, along the posts of support B, sincesleeves C surround these posts and may be fixed thereto in any positiondesired by means of suitable setscrews.

The upper horizontal tube G is outwardly bent so as to facilitate,asmentioned, its location at the back ofthe car seat.

The small armchair itself comprises a back D and two side ortions D,,D,, as well. as a seat E preferably made of plastic material which isflexible and washable.

The seat E is provided with a front extension E which serves as a coverfor the footrest.

Parts D, D, and D are fixed respectively to plates Q, R, P of molded,rigid, plastic material, which are arranged on the outer surfacesofthese parts.

These plates are provided with axially spaced hinging sleeves Q,,, R,and P which are arranged to receive hinge pintles M which are also soformed so as to constitute the elements for mounting the small armchairon the vertically adjustable slide or on the back of a car seat. PlatesR and P are formed, additionally, with horizontally extending sleeves Rand P,,, respectively, on their inner surfaces adjacent their upperedges. These sleeves receive the arms of a substantially rectangularU-shaped frame S supporting tray T. These arms are secured in adjustedposition in their respective sleeves R and P,, by means of setscrews Vthreaded through apertures in the respective sleeves. Thus, tray T maybe adjusted longitudinally of the small armchair or may be completelyremoved therefrom.

On their lower edges, slide plates R and P are formed with suitablemeans for receiving the hook ends F, ofa frame F for supporting seat E.The lower edges of these plates R and P are further formed withrespective sleeves R and l for receiving the arms H of a substantiallyrectangular U-shaped footrest H. Arms H may be secured in adjustedposition in their respective sleeves by means of setscrews V" threadedinto the sleevesyand the footrest is completely disengageable from theplates R and P. Handles Z are provided on the outer surfaces oftheplates R and P.

Frame F for supporting seat E includes a longitudinal frame member whichis formed with an elongated slot F whicl slidably receives a threadedpin on the underside of seat E, thi pin being provided with a suitablenut whereby seat E may bt secured in adjusted position on frame F or maybe completely removed therefrom.

The frame S supports a plate 8, also made of metal, for the child toplay, and is adapted to support also a tray T of plastic material whichmay be connected thereto (see FIG. 7) by means of projections T Theunderside of tray T, adjacent its forward edge, is provided withformations cooperable with the bight of frame S, and, adjacent the rearedge of its under surface, tray T is provided with a slotted bracket T,or a strap or the like which may also extend through a slot in theextension E ofseat E (See H08. 5 and 7).

A U-shaped tube U is pivoted to brackets on frame F and normally restsagainst the under surface of seat E. When the small armchair is removedfrom the slide C-G, the chair may be supported on the floor or the likeby swinging the bracket U downwardly so that this bracket, incooperation with the footrest H supports the small armchair.

The elements M, as best seen in FIGS. 6 and 9, have relatively elongatedrectilinear legs which extend through the hinge portions on the backplate Q and the side plates R and P to pivotally interconnect .theseportions. However, such pivoting is prevented by engagement of the hookends F, of frame F with the side plates. The elements M are retained inposition by means of cooperating setscrews and nuts V', as best seen inFIGS. 6 and 8. The upper ends of these elements M are bent to formrelatively large hooks M, which may be used to support the smallarmchair on the back ofa car seat. Intermediate its ends, each element Mis provided with a smaller hook M in the form of an apertured angleplate, and these hooks M engage over the upper crosspiece G of thevertically adjustable slide to releasably support the small armchair onthe upright framework B. The elements M are rotatable so that either thehook M, or the hook M, may project rearwardly from the small armchair.When the elements M are swung to a position wherein the hooks M projectrearwardly, the hooks M, rest in grooves or recesses Q ofthe plate 0.
